OUR VERDICT
Verdict: start with the free course; pay only if you want projects reviewed. Udacity’s Introduction to Python Programming is free, beginner-friendly and about 14 hours of lessons on data types, data structures, control flow, functions and scripting. It has no certificate and no graded project. If you want those, Udacity sells two paid follow-ons: a 21-hour Introduction to Python for Data Science course with one project, and a 44-hour Introduction to Python Nanodegree that prepares you for the PCEP and PCAP certification exams. Both come with Udacity’s subscription, $125 a month today. Our score for the free course: 3.8 out of 5.

WHAT CHANGED
Our earlier review described a paid Introduction to Python Nanodegree with a US Bikeshare project and a $307 monthly price. That version is gone. The program ID (nd771) now belongs to a different, certification-prep Nanodegree, and Udacity has added a separate data science course with the same name. This review covers all three as they are sold today.

“Udacity Introduction to Python” now means three different products. Here is how they compare, with Udacity’s own figures from 24 October 2026:
| Intro to Python Programming | Intro to Python for Data Science | Intro to Python Nanodegree | |
|---|---|---|---|
| Type | Free course (ud1110) | Paid course (cd0024) | Nanodegree (nd771) |
| Length | About 14 hours of lessons | 21 hours | 44 hours |
| Projects | None graded | 1 (NASA exoplanet data) | 3, mentor-reviewed |
| Certificate | No | Course certificate with the subscription | Nanodegree certificate |
| Learner rating | 4.5 from 737 reviews | 4.7 from 76 reviews | No reviews yet |
| Last updated | 25 May 2026 | 26 Aug 2026 | 13 Oct 2026 |
| Price | Free | $125 a month (subscription) | $125 a month, or $499.50 one-time |
Python itself is the reason these courses are popular. It is the language most beginners now learn first, and it is used for automation, data analysis, web back ends and machine learning. Which of these three is right for you depends on one question: do you need someone to review your code, and a credential at the end, or do you only need the lessons?
In short: complete beginners should start with the free course and decide after a week whether they enjoy it. People heading for data analysis get the most from the data science course, because its project uses the same Pandas workflow analysts use at work. People who want a certification on their resume, or who learn best with deadlines and feedback, should look at the Nanodegree.
About the Udacity Introduction to Python Course
The free course, Introduction to Python Programming, is the one most people mean, and the one our links open. It is taught by Juno Lee, a curriculum lead at Udacity, and sits in Udacity’s School of Programming and Development. There are no prerequisites beyond reading English.
The format is short videos followed by in-browser quizzes and coding exercises after almost every concept. That rhythm is its strength: you write code within minutes of starting, and each lesson builds on the last. Its weakness is the end point. When you finish, there is no project, no reviewer and no certificate. Udacity’s help center describes its free courses as a textbook anyone can read, with no confirmation that you read it.

Job Scenario
Be realistic about what an introductory course does for a career. Fourteen hours of Python fundamentals will not get you hired on their own, from Udacity or anyone else. They are the first step toward roles that use Python heavily, such as data analyst, back-end developer, test automation engineer or machine learning engineer, and each of those needs months of further study and a portfolio.
Two of Udacity’s paid options move you further along that path. The data science course ends in a real data project you can show. The Nanodegree prepares you for the Python Institute’s PCEP and PCAP exams, which give employers a standard benchmark for entry-level Python skill. If you are deciding between Python and another first language, our coding for beginners guide compares the options.
Cost and Duration of the Udacity Introduction to Python Course
- Introduction to Python Programming (free): $0. Udacity’s lesson estimates add up to about 14 hours: 3 each for data types, data structures and control flow, 2 each for functions and scripting, and 1 for the optional advanced topics.
- Introduction to Python for Data Science: 21 hours, included in Udacity’s subscription: $125 a month (50% off the $249 list price during the current sale, with code HALLOWEEN50). It is not sold as a separate one-time purchase.
- Introduction to Python Nanodegree: 44 hours, on the same subscription ($125 a month, or $423 for 4 months as a 4-month bundle), or $499.50 as a one-time purchase.
A subscription now opens Udacity’s whole catalog, so if you plan to take both paid options, do them in the same month or two. At ten hours a week, the data science course takes about two weeks and the Nanodegree about a month. Udacity refunds a first purchase only within seven days (14 in the EU). The Python Institute’s exam fees are separate from Udacity’s price: PCEP starts at $69 and PCAP at $295 on the Institute’s site.
Prerequisites of the Udacity Introduction to Python Course
- Free course: none. It starts from zero.
- Data science course: basic arithmetic, plus logarithms and exponents for the statistics lessons.
- Nanodegree: basic GitHub, because the third course uses GitHub Copilot in VS Code. The Python itself starts from the beginning.
Syllabus of Udacity Introduction to Python Course
Free course: Introduction to Python Programming
- Why Python Programming: an overview of the course.
- Data Types and Operators: built-in types, operators, type conversion, whitespace and style.
- Data Structures: lists, tuples, sets and dictionaries, with more built-in functions.
- Control Flow: conditionals, loops and list comprehensions.
- Functions: scope, documentation, lambda expressions, iterators and generators.
- Scripting: setting up a local environment, running scripts and handling input.
- Advanced Topics (optional): more on iterators and generators.
Paid course: Introduction to Python for Data Science
The same Python fundamentals, then four lessons on data: installing packages with pip, loading and exploring data in Pandas and Polars, filtering, grouping and pivot tables, and charts that show distributions, trends and outliers. The project, “Are We Alone in Space?”, has you load, visualize and analyze NASA’s exoplanet data.

Nanodegree: Introduction to Python (with certification prep)
| Course | What it covers | Project |
|---|---|---|
| Beginner Python PCEP Certification Prep (21 h) | Variables, Boolean logic, control flow, data structures, functions, exceptions | A Data-Driven Approach to AI and Python: turn raw Amazon review data into insights |
| Certified Associate Python Programmer (PCAP) | Modules and packages, exceptions, object-oriented programming | Build a Python CLI to Predict Startup Success: OOP, file I/O and exported reports |
| GitHub Copilot with Python (6 h) | Prompting, code completion, chat, edit and agent modes, test generation | Refactoring Legacy Code with Copilot: modernize a legacy Sudoku game and add features |
The Copilot course is the unusual part. Few beginner programs teach you to work with an AI coding assistant, and doing it after you can write Python unaided is the right order.

Pros and Cons
Pros of Udacity Introduction to Python Course
- The free course is genuinely free, with no trial or card required, and rated 4.5 from 737 learners.
- Short lessons with an exercise after nearly every concept keep you writing code.
- Clear upgrade paths: one data project, or a certification-prep Nanodegree with three reviewed projects.
- The Nanodegree adds GitHub Copilot practice, which most beginner courses skip.
Cons of Udacity Introduction to Python Course
- The free course has no certificate, no project and no reviewer.
- At about 14 hours it is much shorter than free alternatives like Harvard’s CS50P, which runs ten weeks and ends in a final project.
- The paid options cost a monthly subscription, and the Nanodegree is too new to have learner reviews.
- Certification exam fees are not included in Udacity’s price.
Advance features of Udacity
What separates Udacity’s paid programs from its free courses, and from most cheaper platforms, is the project review. A person reads your submitted project and returns written feedback, and you resubmit until it passes. The subscription also includes access to the full catalog, career coaching and interview preparation, and a certificate for each program you complete.
Two caveats from current learners. Review times vary: Trustpilot reviewers mostly praise the projects, but the most common complaint is a review left pending for weeks. And on subscriptions bought since September 2023, classroom access ends when the subscription does, even after you graduate; you keep access to the projects you submitted. Udacity holds 4.5 out of 5 on Trustpilot from 3,414 reviews.
About Instructors
The free course is taught by Juno Lee, listed on the page as a curriculum lead at Udacity. Learners on the course page mostly describe it as a clear first course; one three-star review sums it up as “Python101!”, which is fair: it covers the basics well and stops there.
The paid options have their own teams. The data science course is taught by Metin Akyol, PhD, a quantitative analyst at Fidelity, with Juno Lee. The Nanodegree lists three instructors: Brian Hough, an AWS DevTools Hero and founder of Tech Stack Playbook; Mark Gardner, a freelance developer and engineering instructor; and Daniel Mease, a senior technical content developer at Udacity. Instructors record the lessons; the people who review your projects are a separate pool of Udacity reviewers.
Is this Udacity Introduction to Python Course worth it?
The free course is worth it for almost any beginner: it costs nothing, and it is a well-paced way to find out whether you enjoy programming. Pair it with a free course that includes graded work if you want proof of your skills. Harvard’s CS50P is free, takes ten weeks, and gives a free CS50 certificate if you score at least 70% on every problem set and the final project.
The paid options are worth it in two cases. Take the data science course if your goal is data analysis and you want one real project and the Pandas basics in two weeks. Take the Nanodegree if you want a recognized Python certification and reviewed projects, and you will finish inside one or two months. If you only want to learn Python as cheaply as possible, the free routes and a Udemy Python course cost far less.
